Terahertz Imaging and Spectroscopy in Cancer Diagnostics: A Technical Review. [PDF]
BME Front, 2020 Terahertz (THz) waves are electromagnetic waves with frequency in the range from 0.1 to 10 THz. THz waves have great potential in the biomedical field, especially in cancer diagnosis, because they exhibit low ionization energy and can be used to discern ...

Terahertz polarization imaging
Optics Letters, 2005 We present a new method to measure the polarization state of a terahertz pulse by using a modified electro-optic sampling setup. To illustrate the power of this method, we show two examples in which the knowledge of the polarization of the terahertz pulse is essential for interpreting the results: spectroscopy measurements on polystyrene foam and ...

Twenty years of terahertz imaging [Invited]
Optics Express, 2018 The birth of terahertz imaging approximately coincides with the birth of the journal Optics Express. The 20th anniversary of the journal is therefore an opportune moment to consider the state of progress in the field of terahertz imaging.
